This unusually large Freckenham gold stater above comes from the famous hoard of Celtic gold coins found at Freckenham, Suffolk, in 1885.

Dug up with around 90 others, it dates to c.25-43AD and has belonged to several well-known numismatic authors, including Bernard Roth, Richard Cyril and Commander Richard Paston Mack, author of The Coinage of Ancient Britain.

The coin will be auctioned on January 13 at Chris Rudd of Aylsham in Norfolk, guided at £1500.
